Looking for low capital, low tech, homebased, ecommerce based, business ideas for retirees with mobility issues that would work during this pandemic in my country?

Hi there,This is not a side hustle, rather a full time, full fledged business. We live in Bangladesh and I am trying to start a small home-based business for two retiree relatives who are in their mid fifties.The business has to be something that is non-techy, low capital (say USD 500-USD 1000 at most; thats not too low, given a fulltime employee with high school diploma costs USD 1400 a year). If it brings in a small steady stream of income (say USD 300 in net profits a month) on a monthly basis, thats fine--no need to be a big business or bring in lots of money. It should also be something that would not require manual labor or lots of movement (like door to door sales, outdoor sales) because they would not be able to do it with their mobility problems and age.We would be operating the business from a Facebook page.Things I thought of:Reselling goods (retail) from Facebook but the profit margin is very low, capital requirement is high and with the pandemic most goods do not sell well.I thought of a food business but that requires licensing and setting up a commercial kitchen and its too expensive to setup. I thought of a customized T-shirt, mugs, posters business but with the pandemic people are saying no one would buy it.Thought of a houseplant busines but there are TOO MANY competitors and margin is almost non-existent. Thought of home decor, but people are saying who has the disposable income to buy it during the pandemic when people are jobless.Businesses that are heavily customer service based wouldn't work. Neither would high skill work such as translation, transcription, typing, letter writing etc---they are not that skilled. They don't have the artistic skill and wouldn't be able to do creative work. Going on youtube, making a podcast or some other charismatic work won't be possible as well.I did start a homemade pickle business but had to shut it down due to the expensive licensing and setup costs. I was in the initial stages of a handicrafts business but had to shut it because the market for handicrafts is negative now given the pandemic.I am particularly interested something that I can manufacture or assemble at my home and resell online on Facebook. But it could be some other business ideas as well.I have been searching for an idea for two years now, and I am close to tearing my hair out because of the lack of progress. I mean TWO years and still not a viable idea!! I have been on Facebook business groups in Bangladesh and still no idea.Can someone please suggest an idea that would work? see hubwealthy.com/wealthy
